MSTR doesn't hold their keys.
Coinbase coupe be swung to the general public as a service... "This quantity of reserves including pension funds, large institutions, and more is dangerous in the hands of a private or public company. It is better for this kind of asset to be managed by the government itself in a more structured manner. The treasury is the right place for this and the US has seen the success over generations. It is in the public's best interest and for the savety of all those who hold these funds."
